Bringing Medication Into Japan: Documents and Customs Requirements
Some prescription medications require documentation before entering Japan.
Get clear guidance on what paperwork and translations are required before entering the country.
When Do You Need a Medical Translation?
You may need a Japanese translation of your prescription, doctor’s letter, or medical records when documents must be understood by customs officials, clinics, pharmacies, or Japanese authorities.
You may need translated prescription documents if customs officials ask you to explain the medicine you are carrying.
Japanese doctors or clinic staff may need translated medical information to understand your medication history.
Overseas prescriptions may not be accepted directly, so translated records can help explain your usual medication.
In urgent situations, translated medication records can help healthcare providers respond more quickly and accurately.
A Yunyu Kakunin-sho application may require supporting medical documents to be prepared or translated.
Restricted or controlled medicines may require clear supporting documents and translations before travel.
Common Medication Types We Assess
Japan's rules focus on the active ingredients in a medication. These are common medication categories travellers ask us about before entering Japan.
Travelling with medication used for ADHD, anxiety, or sleep disorders.
Travelling with insulin, glucose monitors, or diabetes supplies.
Bringing medication that requires syringes, injection pens, or needles.
Travelling with multiple prescription medications for long-term health conditions.
Travelling with emergency allergy medication such as an EpiPen.
Carrying medication related to chemotherapy or ongoing cancer care.
Rules for Bringing Medication Into Japan
Japan allows many medicines to be brought into the country for personal use, but the rules depend on the medication type, active ingredient, quantity, and whether the medicine is controlled or restricted.
Most prescription medications can be brought for personal use in small quantities.
Bringing more than a 1-month supply may require advance approval, known as Yunyu Kakunin-sho.
Some medications, including certain ADHD or anxiety medications, are restricted or prohibited in Japan.
Carry a prescription or doctor’s letter, with a Japanese translation if needed.
Restricted medications may be delayed, refused entry, or confiscated if required approvals or supporting documents are not available.
Preparing the Right Documents Before Your Trip
The documents you need depend on your medication, quantity, and whether the medicine requires advance approval.
Bring the original prescription or doctor's letter explaining the medication, dosage, and medical condition.
Prepare a Japanese translation if your prescription or doctor's letter is not written in Japanese.
Apply for a Yunyu Kakunin-sho, also known as a Yakkan Shoumei, if your medication or quantity requires advance approval.
Present your medication and necessary supporting documents to customs officials when entering Japan if requested.
When Do You Need a Japanese Translation?
Medical documents issued outside Japan are usually written in your native language. Japanese authorities, customs officials, doctors, or pharmacists may need a Japanese translation to understand the medication and its purpose.
A translation is likely needed when:
- You are submitting medical documentation as part of a Yunyu Kakunin-sho application
- Customs officials need to understand the medication you are carrying
- You have lost or need to refill your prescription while in Japan
- You need to speak with a doctor or visit a hospital in Japan

When Things Don't Go to Plan: Real-World Medication Travel Scenarios
These situations are common and preventable. Understanding the rules before you travel helps avoid unnecessary delays or complications at customs.
Running out of long-term medication during an extended stay can lead to clinic visits, repeat tests, and treatment delays when overseas prescriptions are not recognised locally.
Many medications for ADHD, bipolar disorder, and neurological conditions are tightly regulated in Japan. Without advance checks and translated documentation, treatment can be interrupted unexpectedly.
When insulin is lost in transit, replacement delays can become dangerous. Clear documentation can determine how quickly help is available.
Injuries and illness can happen at any time. Without translated medical information, emergency care and triage decisions may be delayed.
Safe needle disposal is regulated in Japan. Travellers using injectable medication need the correct documentation and process understanding in advance.
In a medical emergency, language barriers can delay treatment. Translated medication records help healthcare providers respond faster and more accurately.
Bringing restricted medication without the correct documentation can result in confiscation, delays at entry, or in serious cases, detention and legal penalties. Final approval rests solely with Japanese government authorities.
